An important practical extension to FORTRAN 77 was the release of MIL-STD-1753 in 1978. [37] This specification, developed by the U.S. Department of Defense, standardized a number of features implemented by most FORTRAN 77 compilers but not included in the ANSI FORTRAN 77 standard. These features would eventually be incorporated into the ...
This standard, designated FORTRAN 77, introduced many new statements into the language. In fact, the previous language standard FORTRAN 66 is a very small document and describes, what is in effect, a subset of most implementations of FORTRAN. For example, the WATFIV and WATFOR-11 implementations are based upon the IBM definition of FORTRAN-IV.
f2c is a program to convert Fortran 77 to C code, developed at Bell Laboratories.The standalone f2c program was based on the core of the first complete Fortran 77 compiler to be implemented, the "f77" program by Feldman and Weinberger.
LAPACK was originally written in FORTRAN 77, but moved to Fortran 90 in version 3.2 (2008). [3] The routines handle both real and complex matrices in both single and double precision. LAPACK relies on an underlying BLAS implementation to provide efficient and portable computational building blocks for its routines. [2]: "
Simply Fortran is an Integrated Development Environment (IDE) for GNU Fortran (which currently implements FORTRAN 77, Fortran 90, Fortran 95, Fortran 2003 and Fortran 2008). [1] The project is maintained by the company Approximatrix, LLC .
SLATEC Common Mathematical Library is a FORTRAN 77 library of over 1,400 general purpose mathematical and statistical routines. The code was developed at US government research laboratories and is therefore public domain software.
Several output formats are supported such as X11, VGA, PostScript, PDF, CGM, WMF, EMF, SVG, HPGL, PNG, BMP, PPM, GIF and TIFF. DISLIN is available for the programming languages Fortran 77, Fortran 90/95 and C. Plotting extensions for the languages Perl, Python, Java, Julia, Ruby, Go and Tcl are also supported for most operating systems.
QUADPACK is a FORTRAN 77 library for numerical integration of one-dimensional functions; SLATEC is a FORTRAN 77 library of over 1400 general purpose mathematical and statistical routines. SOFA is a collection of subroutines that implement official IAU algorithms for astronomical computations. Both Fortran and C versions are available.
